49-268 12mm Dia. x 15mm FL; VIS 0deg Coated; UV Double-Convex Lens VIS 0deg 425-675nm
This is a 12mm diameter, 15mm focal length double-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is made from fused silica, a material with the material ID mal-1965, and is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens features a standard coating on both the front and back surfaces, specifically the 'edm vis-0 std curve' coating. This coating is designed to enhance the lens' performance within the visible light spectrum, providing improved transmission and reduced reflection.
The lens' geometry is characterized by a thickness of 1.57mm at the edge and 4.5mm at the center. The first radius of curvature (R1) is 13.01mm, while the second radius of curvature (R2) is -13.01mm, indicating a convex-convex shape. The back focal length (BFL) is 13.37mm, and the effective focal length (EFL) is 15mm.
The lens is available for purchase directly from the Edmund Optics website, and at the time of data collection, it was listed as in stock. For more detailed specifications and purchasing information, please refer to the provided weblink.
